Answer:
We can represent this question as a system of equations
Let
x = number of dark clothes
y = number of light clothes
L = total number of clothes
The number of dark clothes is three more than twice the number of light clothes
x = 2*(y) + 3
The laundry is 60% dark clothes.
x = 0.6*(L)
Answer:
x=3+2y and 2x=3y
Step-by-step explanation:
Let the number of dark clothes be x
and that of light clothes be y
It is given in the condition that
x= 3 more than twice of y
x=3+2y ------------------------------ ( I )
Also it is given that 60% clothes are dark
Hence
[tex]\frac{dark}{total clothes}=\frac{60}{100}[/tex]
[tex]\frac{x}{x+y}=\frac{3}{5}[/tex]
doing cross multiplication
[tex]5 \times x = 3 \times (x+y)[/tex]
[tex]5x=3x+3y[/tex]
2x=3y ----------------------------------- (II)
Hence equation (I) and (II) represent the two conditions given in the problem.
